Infernal Devices

Infernal Devices book 1: Clockwork Angel by Cassandra Clare

I knew when I finished books 1-5 of The Mortal Instruments series that I would read this series as well. It is set in Victorian England, so the characters aren't the same, but we are introduced to some of the ancestors of the characters we love.

This book focuses on Tessa, who is not a Shadowhunter, but is a Downworlder of some kind. She can change into other people, if she has something that belongs to them.

Tessa comes to England to be with her brother, Nate. He is the only family she has left. When she gets to England, she is duped by the Dark Sisters into believing that they will be bringing her to Nate. Instead, they keep her for their own nefarious designs, that were set out by the Magister.  One particularly bad day, Will Herondale rescues Tessa. Tessa believes something bad has happened to her brother, and the Shadowhunters vow to help her find him.

Find him they do, and ultimately discover that he is aligned with the magister.
